Once, back in the Paleolithic era, a hunter unknown to us scratched the figures of people and animals with a sharp stone on the wall of the cave. The centuries passed … the writing appeared. Signs were carved on stones, painted on papyrus. In Assyria, the signs were written with a sharpened stick on the plates made of wet clay, which were then fired.
In the Middle Ages, people learned to write with pieces of lead with sharpened ends. Since the XIV century, artists in Europe used lead and tin, as well as silver pins for drawing. The great Botticelli made many of his drawings using such pins.
In the middle of the XVI century, English shepherds from Cumberland found a fairly soft and brittle mineral in the ground. The rocks were taken for the deposit of the lead because of the color.
